Abstract: In an apparatus and a process for treating a product with a liquid cryogen, the liquid cryogen is supplied to an removed from a processing chamber (11) containing the product to be treated, cryogen vapor is supplied to said processing chamber (11) from a source (19) containing the cryogen vapor at superatmospheric pressure and the cryogen vapor is withdrawn by interconnecting upon the removal of liquid cryogen the processing chamber (11) and a compressing means (75, 77, 79) in fluid communication to thereby recover said cryogen vapor. The pressure at said compressing means (75, 77, 79) is monitored and vapor is supplied from said sources (19) to said compressing means (75,77,79) when said pressure at said compressing means is at or below a predetermined pressure, said predetermined pressure being less than superatmospheric pressure at said source. Overheating the compressing means (75, 77, 79) is avoided by the invention when process conditions or equipment malfunctions cause curmailment or stoppage of the cryogen vapor flow from the treatment chamber (11) to the compressing means.

Abstract: To manufacture cooked and smoked meat having a taste of ham, boned poultry meat is used and this is processed in a similar manner to pigmeat by means of spicing, salting, kneading, moulding, cooking and use of a smoke house. In order to obtain a meat similar to that of a traditional ham, the proportion of hand-boned meat to machine-boned meat must be at least two to one, preferably 4/5 to 1/5. A meat of this sort makes it possible to reduce the surplus of chicken meat and enables those persons who are forbidden from eating pigmeat to have a meat with a taste similar to that of pork ham. Moreover, the energy value in joules is considerably reduced.

Abstract: In a communication system interconnecting a plurality of processors (8 ...13) by a communication link (1) through individual communication stations (2...7), a mechanism for remote processor initialization is provided which enables a specific frame exchange procedure for the transfer of initializing information from a source processor to an acceptor processor. All communication stations are basically equal. Means (104, 108,110) are provided in each station to automatically cause generation and transmission of a request initialization frame under certain conditions if the attached processor is an acceptor, and to cause transmission of initializing information transfer frames between a start frame and a termination frame if the attached processor is a source and the respective station received a request initialization frame. Each station has indicator means (127, 128, 129, 171, 172, 173, J1, J2, J3) which can be set to indicate the type of the attached processor to ensure that initialization frames are generated and handled appropriately.

 a) electrolitically treating the piece, in absence of the metal salts, in an electrolyte of low dissolution capacity and exhibiting a chemical activity inferior to the activity equivalent to a concentration of 4 g:l of H2SO4, by applying an alternating current having a peak voltage preferably of 55 to 85 volts and a current density of less than 0,3 Amp/dm<2>, which alternating current is derived from a polyphase network or from the secondaries of a transformer of a polyphase network; in such a manner that that the positive and negative half-cycles are made to conduct with the same angle of conduction and both being variable according to the necessities, and a cycle of the first phase is followed by the second consecutive cycle of the second phase and by the third consecutive cycle of the third phase and soon until the number of phases is completed, thus balancing the distribution of the charges between the phases of the polyphase supply system; and
 b) electrolitically colouring the treated piece in an acid electrolyte containing the metal salt(s), using alternating current with a peak voltage preferably from 55 to 85 volts derived from the same source as the corresponding alternating currente applied in the preceding step.

Abstract: A jet printing apparatus is shown having a reservoir for storing printing medium. A perforate member having at least one surface which is exposed to the printing medium in the reservoir with the ink entering the perforations. A drive motor effects relative movement of the perforate member past a printing station having a fluid jet with a plurality of nozzles. Electrically controlled valves selectively supply air to the nozzles to eject printing medium from the perforate member onto a printing substrate. In one embodiment, the perforate member is a cylindrical mask having spaced columns of perforations which are successively aligned with the fluid jet nozzles at the printing station. In another embodiment, a mesh belt having perforations is moved between the fluid jet nozzles and an orifice plate which has orifices aligned with the nozzles of the fluid jet. Air from selected nozzles ejects ink from the perforations through an aligned orifice opening onto the printing substrate.
